Kessler. No. 1,008,970 1 01 l both granted Nov. ll.

matter ol the above patents comprises a body metal and a plating of gold. .ln aeeordauee with the Kessler patent the eomposite toil is termed by passing a, toil ol the body metal and 'l'oils of gold through rolls so as to unite them by pressure. The toils are assembled between papers and passed with the papers through rolls. This taeilit'ates the handling of the toils and proteets them during; the rolling operation. in aceordanee with thecKessler proeess the papers are entirely separate, and diit'lieulty has therel'ore been experienced in the practi all working oi the proeess due to the tart that the papers shilted relatively during the rolling operation eausing not only in'iperfeet union oi the toils. but. exposing the toils to the rolls and eausingz them to Sll('l\' thereto. Hueh a shifting ot' the papers also caused eonsiderahle waste in trimming tor the re as son that one paper would projeet over the other rmulerinp; it neeessary to trim otl' eonsiderable material alon one edge to produee a straight edge to trim 'trom.

The objects of this invention are to improve the proeess ot' uniting toils into a eomposite toil so as to facilitate the handling ol the foils and the paper, to prevent shitting and wrinkling during;- the rolling op" eration. and to prevent waste and prepare the toils tor trinnning.

The invention will he described in eonneet-ion with the aeexmunurving; (lawings in \Vllif'lii Figure l a 'diagrammatieal view of a pair of rolls. Fig. 2 is a perspective view showing the means for su 'n'mrtingthe :t'oilsduring" the rolling operation, Fig. 3 an edge View of Fig. 2 showing the supporting means'tolrled. Figs. l. 5 and 6 are perspective views; showing other forms of support The eom )osite loil 'tormin the subeet 'viate t is a partial seetion ing means, and Fig. through the foils and the st of Figs. 52 and 3 showing t lion in the supporting mea he passed through the rolls.

lleterring to Figs. 2 and f2, desig irate two sheets of paper or other suit-able material joined or att-urhed together at 13. lo the actual eenstrut ion, a single sheet ilorming the parts 12, 12 is pertkirated at about its middl as shown. and the sheet is folded on-the perforated line. The result. will be two sheets attaehed or joined along, one edge 13. and since theetlg'e 's mrtorated the sheets will he joined or attached at sepa rated mints.

i iiporting means he toils in posins and reatil; to

in the operation the toils ol' the hody metal 10 and of the surface metal ill are 2 1211s platted together liietween the sheets i shown in Fig. 7 with the edge oi the toils abutting against the pertoiarted e ge L3. The assen'ihled foils and sheets 12 i 1 passed through the rolls 1 with the edge .13 ioremost. In view of the fact that the sheets are so attael'ied, the .fllQQtS and toils (an be haudleefl more, conveniently than it the sheets are separate. The sheets and toils will not wrinkle during the rollingop eration in view of the tact that the sheets are attaehed along; one edge thereby preventing shitting. it is advantageous to perforate the edge 13 so as to eouueet the sheets at separated points, as this will ohwrinkling; oil" the paper along the folded edge. l the sheets are, merely tolded without mrforating the paper will he wrinkled along the folded and this Wlll in t urn rouse wrinkling: oi" the thin foils along their edge. and thus prevent. proper union. Notonly will this jireemiure prevent shifting and Wrii'ilding ot' the sheets and the foils, but it will taeilitate trimming. The eomposite toil as passed from the rolls will be positioned with one edge abutting against the edge '13. This edge can there I tore. be used as a guide in trinnning: so that the trinnning out; ean be reduced to a. minimum, thereby reducing waste. The toils with their retaining sheets as dir leharpged from the rolls (and trimmed along the folded edge) can he stacked up against a eutter and cut into suitable piee The proeedure in rolling is ditierent. mom that in the Te sler patent. in the hfessler patent th. it 11s are first passed together with paper between rolls then passed hare adhesive.

' anee with this invent-i on the sheets 12 sheets i2 is folded over and against the through the rolls, and then rough paper through the rolls the fiber and soft-en the foil.

passed with to break up In accord sufiiciently grain to soften. the foil and. suf'oientiy hard so ing operation may lie performeiil and completed with the ioils between the sheets. The toiis i thee pd rolled untii they are united to forth ti finished product. The sheets are rougmi, with oche'r-to prevent sticking ot'the toils to the sheets. The sheets and foils as from the rolls are then trimmed to finished size.

rd show other methods and hing or joining the edges of the sheets in. in 3: t the edges 15 are attached by a narrow line of paste. may he done in any sui table manner. lVhere the paper forming the sheets 12 is thin and is with oe .ier dampened With gyieerin, the of the will stick together as they are passed through the rolls so that no .additimuil paste will be required in this case. In Fig. 5 narrow strip of papei" 16 is folded or is one of the edges of the sheets 12. This strip may he placed over the edges or the sheet with or Without the use of an adhesive, as a matter of foot, the rouge or ooher coating on the sheets will also act. as an adhesive as explained above. The strip wili enter the bite of the rolls first and will serve to hold the edges of the sheets 19. from shitting.

due to the fact that the arts oi strip 18 extending on opposite sides of the sheets are secured together along their roli ntering edge. In Fig.6 one of the other sheet shown at 17 Here also the lap 17 may be provided with an adhesive to attach it to the lower sheet 12, or the ocl'ier eoating may be relied upon to furnish the The sheets 12211-0 thus secured trjgether along one edge by the adhesion ot' -the lap 17 w h the lower sheet 12. In Figs. 5 and 6 the sheets 12 are attached along their edges either by a separate folded strip, or by a lap extending over a tree edge of one or the sheets. The "wrinkles forming along the-foldededge of the strip or lap are of l that the entire rollare therefore assembled between This will be separated therefrom by the sheets time the sheets themselves. At the same are attached along one edge so as to retain the foils and sheets in assembled relation and prevent their shifting. It will thus be seen that the edges of the sheets 12 in all the different. forms are so attached. that wrinkling along the obviated.

It is obvious that various changes maybe made in the details of the process within the scope of the appended claims withoutdeparting from the spirit of this invention;

1 it is therefore to be understood t-hat'this invention is not to be limited to the specific details described and shown.
